25 Claims.

This invention relates to a lighting construction and has particularreference to floodlights.

More particularly this invention relates to floodlights giving forth ahighly concentrated beam surrounded by a dlflused flood of light, com-'prising a main reflector attached to a housing hood in which is secureda socket for supporting a lamp to extend downwardly into the reflector,and an inner reflector positioned partially about the rear of the lampfor reflecting a concentrated beam of light. The socket-is adapted to bepivoted in the hood so as to adjust the position of the lamp withrespect to the inner reflector. The

whole construction is secured to a stationary support by a pivotallyadjustable bracket. I

An object of this invention is to provide a floodlight for the generallighting of a large area, such as filling stations, beaches, railroadand factory yards and the like, and simultaneously spot lighting adefinite location or object which it is desired to make stand out morebrightly than the surrounding area.

A further object of this invention is to provide a floodlight of thetype referred to above, in which the relative position of the lamp andreflectors may be easily altered. By altering the relative position ofthe lamp and the reflectors, the highly concentrated beam of light maybe more or less concentrated, as desired, depending upon the area orobject to be particularly illuminated and the purpose of theillumination. This is accomplished in the present device by having thetwo reflectors fixedly secured to a hood and a socket for receiving alamp attached to a cap member which is pivotally mounted on the hood.Thus when the cap is tilted, the position of the lamp with respect tothe reflectors is altered.

A still further object of this invention is to provide a floodlightwhich will be durable, efllcient, weatherproof and easily adjustablelaterally and vertically. The lateral adjustment is accomplished bymeans of a bracket on which the hood is pivotally mounted. In thepresent construction the lead wires are completely enclosed in a wiringchannel which leads from the support on-which the structure is mountedto the cap positioned on top of the hood.

Further objects and advantages will be more readily apparent from thefollowing description when taken together with the accompanyingdrawings, in which Figure 1 is a central vertical cross-sectional viewof a floodlight embodying the present invention, shown attached to astationary support;

Fig. 2 is an enlarged cross-sectional view of the pivotally mounted capto which the socket is attached, showing the cap and socket pivoted tomaintain the lamp further from the inner reflector than the positionshown in-Figure 1;

Fig. 3 is a vertical cross-sectional view of the cap pivoted on thehousing hood and the -means for attaching the socket to said cap, takenon line 3--3 of Fig. 2;

Fig. 4 is a front elevational view of the inner reflector;

Fig. 5 is a top plan view, partially in section, of the inner reflector,showing. the securing ring thereon;

Fig. 6 is a top plan view, partially in section, of the main reflector;and

Fig. 7 is a detailed view oi a portion of the inner reflector and thepositioning flange thereon.

Referring more particularly to the drawings, the construction showncomprises a main reflector l and an inner reflectorl, both secured tothe housing hood 3. The main reflector i is I scoop-shaped, having asubstantially flat rectangular top portion 4 rounded at the sldesandrear, a rounded rear end portion 5 and substantially triangular shapedsides 6 having the apex thereof adjoining the .front end I of the topportion 4. The inner reflector 2 is substantially parabolically-shapedand is provided with shallow flutes 8.

The main reflector l intercepts and redirects upon the entire area to beilluminated light not utilized by the inner reflector 2. Whileefliciently redirecting the light, the main reflector I also acts as ashield at angles where glare would be objectionable. The light is cutoil sharply in a long straight line at the top edge of the beam andwhile the cut-ofi at the back and sides near the back is close beneaththe fixture, considerable diffused illumination is provided by theoverhanging portion of the main reflector for some distance behind thecut-off. The cut-011 at the sides of the main reflector l is such thatwhen the unit is mounted on a 90 corner, and turned in at 45, no glareis experienced at any distance along the sides of the 90 angle. Thismakes the fixture exceptionally suitable for use on corners.

The inner reflector 2 is designed to intercept an adequate quantity oflight to make an object or area stand out more brightly than thesurrounding area illuminated by the light reflected from the mainreflector. The shallow flutes 8 are provided to avoid the striations orstreaks which are present where any large irregular light source is usedwith a polished reflector. By adjusting the inner reflector 2 withrespect to the mainreflector I, which may be done during theconstruction of the device by altering the angle between the innerreflector 2 and the flange I2 thereof,

the highly concentrated beam of light from the inner reflector may befocused on any area or object within the area lighted by the mainreflector I, or, if desired, it may be focused on an area or objectwithout the area lighted by the rays from the main reflector.

The main reflector l is provided with an opening I in the top thereofwith an inwardly extending flange il about said opening, and the innerparabolic reflector 2 is likewise provided with a hole II in the topthereof with an inwardly extending flange about said opening "I, throughwhich openings a lamp extends into the reflectors. A positioning flange2a is positioned about the sides of the inner reflector 2. The tworeflectors are attached to the bottom of the housing hood 2, which isopen at the top, by means of screws I2 extending upwardly through theflange I2 of the inner reflector 2,'the flange ll of the main reflectorI, and threading into the. bottom of the housing hood 3. Gasketsll andI! are positioned respectively between the top of the housing hood 2 andthe flange II and between the flange II and the flange l2.

A cap portion I8 is pivotally mounted on the upper surface of thehousing hood 2. The housing hood 2 is formed withtwo opposite sidesextending upwardly above the remainder of the hood to form a fulcrum I!on which the cap It pivots, with projecting portions ll of the cap i6resting on the fulcrum il. Thumb screws I! are inserted through openings20 in the cap it and thread into threaded recesses 2i inthe housing hood3, the threaded recesses 2| being positioned in the upper end of saidhousing hood 2 intermediate the fulcrum portions I], so that bytightening one of the thumb screws i9 and loosening the other, the capmember I3 pivots on the fulcrum I1 and is flxedly positioned at alltimes. If desired, the fulcrum portions may be formed on the bottom ofthe cap l6 and pivot on the top of the hood, which would then be madeflat.

A socket 22 is flxedly secured to the cap portion I 8 by means of screws23 extending upwardly through the upper section of the socket 22 andthreading into the projecting portions l8 of the cap IS. The socket 22is adapted to be inserted into the housing hood 3 through the opening inthe top thereof, the housing hood being made sui'iiciently large forthis purpose. Thus the socket 22 may be wired and secured to the cap i6before it is inserted in the fixture. Thus when the cap I is pivoted onthe housing hood 3 by means of the thumb screws IS, the socket 22attached thereto pivots with it and causes the lamp supported in thesocket to be moved toward or away from the inner reflector. 2, andthereby affects the concentration of the beam caused by the innerreflector 2.

A novel securing means is provided for pivotally mounting the lightingflxture onto a stationary support. A securing bracket 25 having atubular portion 28 is inserted over the top of a vertical pipe 21 with aflange portion 28-resting on top of the pipe. Set screws 29 hold thebracket 25 from rotating on the pipe 21. A channel member 30 is providedon the top of the securing bracket 25 for guiding the lead wires fromthe top of the pipe 21 to the cap IS. A cover 3| fits over the top ofthe channel section and is secured thereto by screws 32, thus providingan enclosed channel from the vertical pipe 21 to the cap ll, throughwhich the lead wires run to the wiring terminals of the socket 22. Arms18 and 24 extend outwardly from the housing hood 2. The arm 22 ispivotally mounted on the outer, upper portion of 5 the bracket 25 bymeans of a bolt ll extending through an opening provided therefor in thebracket 25 and through an opening in the arm 22, the bolt being held inplace by a nut 20. The arm 34 is arcuate. having a radius drawn on thecenter of the bolt 28. An arcuate slot 21 drawn on the same center isprovided in. the arm 24. A bolt 38 is extended through an openingprovided therefor in the bracket 2! through the slot 3! and a washer I9.Anut III is threaded onto the end of the bolt 28 over the washer 2!. Inorder to pivot the lighting flxture, it is only necessary to loosen thenut 40 and move the flxture forwardly or backwardly until it is indesired position and then tighten the nut ll, and a lateral and verticaladjustment may thereby be obtained with a minimum of efl'ort.

It is a simple matter to wire and mount the flxture, which is done asfollows; The tubular portion 26 of the bracket 2|, which supports the 2fixture, is inserted over the lead wires and over the end of the pipe 21until flange 28 seats on the top of the pipe. The flxture is thus heldon the end of the pipe and need not be further supported. The lead wiresare connected'to thesocket 22 which is then attached to the top I. Thesocket is inserted in the top'of the housing hood 2 and the cap i6attached thereto. The cover II is then secured to the bracket 2' and thewiring is complete. Nothing further remains to be done except to aim thefixture, that is, so adjust it that the light will be pointed in thedesired direction. The lateral adjustment is made by rotating thebracket 25, until it is in desired position, and tightening the screws29. The horizontal adjustment is made by loosening the nut ll andpivoting the fixture about the bolts 25 until the flxture is properlyaimed and then tightening the nut ll. The fixture will thenremain inthis position until it is again adjusted.

It may be preferable to employ a short section of asbestos wire adjacentthe socket 22. When this is done, the asbestos wire may be connected tothe socket and the whole fixture assembled before it is mounted. Then inwiring the flxture after the bracket 25 is mounted on the pipe 21, it isonly necessary to splice the'short section of asbestos wire extendingfrom the fixture to the lead wires extending through the supportingpipe. 55

This application is filed as a continuation and substitute for myapplication, Serial No. 452,233, filed May 14, 1930.
